Wow, that does go for a fair amount nowadays. It's a great album, too - just four tracks of long, evolving, hypnotic drones. It promises to facilitate travel through time and it delivers, as you often end up one hour in the future before you know it.
There doesn't seem to be an official release still available, but I expect it's not actually that hard to get hold of if you know where to look. If you were to do something like Google "Coil Time Machines mp3" or something like that, you never know.
